A surge protector functions similarly to a power strip, but in addition to allowing more devices to be plugged into one outlet, it protects electronic devices from power spikes and power surges. Both spikes and surges can be caused by lightning strikes, power outages, tripped circuit breakers, short circuits, etc.
What is an electrical surge?
In general a surge is a transient wave of current, voltage or power in an electric circuit. … Surges, or transients, are brief overvoltage spikes or disturbances on a power waveform that can damage, degrade, or destroy electronic equipment within any home, commercial building, industrial, or manufacturing facility.
How do you protect an electronic device from electrical surge?
3 Ways To Protect Electronics From Power Surges
- Get an electrician to survey and test your home’s grounding system.
- Protect your electrical service entrance with a surge device. It can be installed behind the meter or at the main electric panel. …
- Protect expensive electronics at their point of use.
What is the purpose of surge protector device in equipment?
A surge protector is an electrical device that is used to protect equipment against power surges and voltage spikes while blocking voltage over a safe threshold (approximately 120 V). When a threshold is over 120V, a surge protector shorts to ground voltage or blocks the voltage.
What causes a power surge in a house?
Power surges can originate from the electric utility company during power grid switching. Another common cause of power surges, especially the most powerful ones, is lightning. Power surges can also originate inside a home when large appliances like air conditioners and refrigerator motors turn on and off.
